淘宝IP地址库:http://ip.taobao.com,里面有REST API 说明。
Delphi XE 调试通过,关键代码如下:
var IdHTTP: TIdHTTP; RequestURL: string; ResponseStream: TStringStream; JO, JData: TJSONObject; begin IdHTTP := TIdHTTP.Create(nil); IdHTTP.ReadTimeout := 0; IdHTTP.AllowCookies := True; IdHTTP.ProxyParams.BasicAuthentication := False; IdHTTP.ProxyParams.ProxyPort := 0; IdHTTP.Request.ContentLength := -1; IdHTTP.Request.ContentRangeEnd := 0; IdHTTP.Request.ContentRangeStart := 0; IdHTTP.Request.ContentType := 'application/x-www-form-urlencoded'; IdHTTP.Request.Accept := 'text/html, */*'; IdHTTP.Request.BasicAuthentication := False; IdHTTP.Request.UserAgent := 'Mozilla/3.0 (compatible; Indy Library)'; IdHTTP.HTTPOptions := [hoForceEncodeParams]; RequestURL := 'http://ip.taobao.com/service/getIpInfo.php?ip=' + edtIP.Text; ResponseStream := TStringStream.Create; IdHTTP.Get(RequestURL, ResponseStream); IdHTTP.Free; ResponseStream.Position := 0; Memo1.Text := ResponseStream.DataString; ResponseStream.Position := 0; JO := TJSONObject.ParseJSONValue(ResponseStream.DataString) as TJSONObject; JData := JO.Get('data').JsonValue as TJSONObject; leISP.Text := (JData.Get('isp').JsonValue as TJSONString).Value; leCountry.Text := (JData.Get('country').JsonValue as TJSONString).Value; leArea.Text := (JData.Get('area').JsonValue as TJSONString).Value; leRegion.Text := (JData.Get('region').JsonValue as TJSONString).Value; leCity.Text := (JData.Get('city').JsonValue as TJSONString).Value; JO.Free; ResponseStream.Free; end;
